A/N: This is with Alternate Snape.
Snape sat in the library pouring over every book he could think of that could possibly tell him what was going on. Yet there was no luck, Snape spent hours he even missed his (or rather the true Snape's) Defense Against the Dark Arts class. Snape didn't know what class to go to in the first place and in the second he didn't care he had to find out what was going on. There had to be some explanation to it because this was no prank. Slytherin would not help his friends pull a prank.
As Snape worked he kept his head closely bent over a book. That's when James, Sirius, and Remus came in. Snape hoped that they were coming to tell him it was all a joke and to come help pull a prank that Remus thought of. Yet this is not what happened.
"Look, it's Snivelus, or should I say Batty?" laughed Sirius.
Realizing that his 'friends' weren't such Snape stuck his nose further into his book.
"Oh grouse!" exclaimed James, "Quite sliming the book up! There are others who might want to use that book."
"If you want it take it," answered Snape in frustration.
"Not after you slimed it!" answered Sirius.
Snape just left, he didn't want to take any more of it and the library did not seem to have the answers. James (his James) was wrong after all, everything could not be answered in the library too bad he couldn't share that info Remus would have loved to hear that having never opened a book himself.
Snape then began to wander the halls having nowhere to go. As he did wander the halls he tried to sort out all that had gone on in the last few hours. Just before dinner Snape bumped into Professor Gribble the head of Slytherin and the Defense Against the Dark Arts teacher.
"Severus, you were missed in class today I assumed that you were possibly in the infirmary during class."
Snape got a little nervous, he knew that Gribble hated Gryffindor especially he and his friends. "I'm sorry Professor, I was – you see I was."
"It is perfectly fine, you are one of my star pupils so don't worry about it, I don't think it would hurt you too much to miss just one class."
Snape was floored, was that truly Professor Gribble?
